Large Shape Staggering in Neutron-Deficient Bi Isotopes
/ Barzakh, A (St. Petersburg, INP) ; Andreyev, A N (JAEA, Ibaraki ; York U., England) ; Raison, C (York U., England) ; Cubiss, J G (York U., England) ; Van Duppen, P (Leuven U.) ; Péru, S (CEA DAM) ; Hilaire, S (CEA DAM) ; Goriely, S (Brussels U., IAA) ; Andel, B (Comenius U.) ; Antalic, S (Comenius U.) et al.
The changes in the mean-square charge radius (relative to $^{209}$Bi), magnetic dipole, and electric quadrupole moments of $^{187,188,189,191}$Bi were measured using the in-source resonance-ionization spectroscopy technique at ISOLDE (CERN). A large staggering in radii was found in $^{187,188,189}$Big, manifested by a sharp radius increase for the ground state of $^{188}$Bi relative to the neighboring $^{187,189}$Big. [...]

A nuclear-decay spectroscopy study of the neutron-deficient isotope At196 is reported where an isotopically pure beam was produced using the selective Resonance Ionization Laser Ion Source and On-Line Isotope Mass Separator (CERN). The fine-structure α decay of At196 allowed the low-energy excited states in the daughter nucleus Bi192 to be investigated. [...]

At the CERN ISOLDE facility, long isotope chains of many elements are produced by proton-induced reactions in target materials such as uranium carbide. The Resonance Ionization Laser Ion Source (RILIS) is an efficient and selective means of ionizing the reaction products to produce an ion beam of a chosen isotope. [...]

A very exotic process of ${\beta}$-delayed fission of $^{180}$Tl is studied in detail by using resonant laser ionization with subsequent mass separation at ISOLDE (CERN). In contrast to common expectations, the fission-fragment mass distribution of the post-${\beta}$-decay daughter nucleus $^{180}$Hg (N/Z=1.25) is asymmetric. [...]
